摘　　要：铁法煤田大兴井田共含煤20层,呈北北东向的条带状分布,煤层比较稳定,煤层气资源丰富。本文通过对煤储层特征即煤层结构和割理密度、割理的组合类型分析,再结合煤层气含量及其控制因素、煤层渗透性和煤储层压力、煤的吸附性综合分析及水文地质条件等资料,选择较为有利的区块,进行小规模的生产试验,为以后的煤层气开发,提供可靠的理论支撑。In Daxing mine field of Tiefa coalfield,it contains 20 layers of stable coal seam. The coal bed methane resource is rich. Based on the analysis of the characteristics of coal reservoirs,such as coal seam structures,cleats density,combination type of cleats,and combined with the content of coal bed methane and its controlling factors,coal seam permeability,coal reservoir pressure,coal adsorption and hydrogeology conditions,the small-scale production test was took in the favorable block. The research can provide reliable theoretical support for the development of coal bed methane.
